Resolving geographic units that do not neatly coincide is a common problem in spatial data analysis. This method attempts to conflate King County Health Reporting Areas (HRAs) to US Census tracts. In the cases where a given tract with entirely within a HRA, that tract receives the HRA’s ID. Where a given tract overlaps multiple HRAs block-level census data is used to determine which HRA ID to assign to the tract.
This method provides three alternatives of block-level counts that can be used:
